Yes, I meant in studio and hi-fi in context of our discussion.
I think everybody knows some albums where, for example, is hard to listen singer voice, lyrics. Is that also is matter of hi-fi? It is hard to believe that it is done with purpose. Maybe my system is not so hi-fi, or maybe producers system is so much hi-fi, that for him everything is fine. I can guess that in this tehnological age most important factor for hi-fi starting to be human factor, leaving techology itself behind. Also interesting, how much building cd, amps and speakers decisions are made by measurements on how much by ear?
